A Multimethod Analysis of Incompleteness and Visual "Not Just Right" Experiences in Body Dysmorphic Disorder.

A Multimethod Analysis of Incompleteness and Visual "Not Just Right" Experiences in Body Dysmorphic Disorder. Behav Ther. 2020 Sep;51(5):764-773 Authors: Summers BJ, Wilver NL, Garratt GH, Cougle JR Abstract Individuals with body dysmorphic disorder (BDD) often report engaging in repetitive behaviors aimed at reducing feelings of imperfection anchored to their appearance. "Not just right" experiences (NJREs) and incompleteness (INC) are constructs related to perfectionism that have traditionally been studied in obsessive-compulsive disorder, though recent research has also linked these phenomena to BDD. We sought to replicate and extend this research via two studies. Study 1 examined BDD symptoms, INC, as well as harm avoidance (HA) in an unselected sample (N = 179); moderate associations were observed between symptoms and both INC and HA. Participants also completed a novel visual NJRE task in which they were shown appearance-related and non-appearance-related images meant to evoke an NJRE response (i.e., discomfort and urge to "fix" stimuli). BDD symptoms predicted reactivity to appearance-related NJRE stimuli above negative affect. Study 2 compared INC, HA, and task reactivity in a BDD sample (N = 50) to nonpsychiatric controls (N = 44). The BDD group evidenced greater INC, HA, and reactivity to both appearance and nonappearance NJRE stimuli, relative to controls; however, group differences did not remain after controlling for age...
